How can I do it manually?
For example: I have a "DataProvider" class with a method:
public static Administrator getAdministrator(Integer id) {
Administrator administrator= (Administrator)
HibernateUtil.getSessionFactory().getCurrentSession().createCriteria(Administrator.class).add(Property.forName("id").eq(id)).uniqueResult();
return administrator;
}
I get the error message. How shall I modify the code?
I tried it with Transaction tx = ... and then tx.begin() tx.commit() -- but
then suddenly hibernate tries permanently to update an object... wired !

Betreff: Re: org.hibernate.HibernateException: createCriteria is not valid
without active transaction
You did not setup your transactions properly.
Or you start your transaction manually, or if you like spring, you can let
spring manage it. (just add your transction annotations to your services,
and, done !
